Answer this question truthfully
### Question: Who is at highest risk for Dysplastic nevus ?
### Response: Clinical data has suggested that the development of melanoma is related to several factors.
Sunlight (solar UV radiation): Too much exposure to sunlight(solar UV radiation) is thought to be the biggest risk factor for most dysplastic nevi. Moles: Although as a benign skin tumor, the mole increases the chance of getting dysplastic nevi, especially for people with many moles. Genetic factors: Epidemiological data show that Whites with fair skin, freckles, or red or blond hair have a higher risk of dysplastic nevi than other race. Immunosuppressive factors: Clinical surveys suggest patients treated with Immunosuppressive medicines such as transplant patients, have an increased risk of developing dysplastic nevus. Previous melanoma: A person with previous history of melanoma has a higher risk of getting another dysplastic nevus. Xeroderma pigmentosum (XP): Patients with XP are at higher risk of dysplastic nevus because they can not repair damage caused by sunlight. Age: Epidemiological data suggest that dysplastic nevus can be found both in old people and in younger people. Gender: Men have a higher chance of developing dysplastic nevus than women.
